its normal price for 10 splitters, and its standar one, i use this maybe 4years and its quite good, try not using this more than 200w, sometimes the socket will burn if not perfectly connected to psu cable

8 pin to 2x8 (6+2) would be better. Just make sure to count the wires to make sure they didnt cheat
by only using 6 wires. They're great for splitting single 8 pin cables to 8+6 or 8+8.

they should be okay for riser feeds.

Always check polarity on them.

And they may never go off settings and max to 190-210 or they may do it tomorrow.

I can go weeks without the issue or it can happen tonight.

Every generation of nvidia or amd since I first used an old amd in my 2010 mac pro to run gou mining for bitcoin in 2012 has had dropping of settings and gone to full power.

the amd 5770 the amd 6790 the  7950 the r 280 the 470 the 570 the vega the 5700

not my lone 6800xt as it has been always on smos.

my gtx 970 1070 2070 3070 3080 all have dropped out and gone to max tdp.

I have used maybe 450 different gpus.since 2012.

and if you miss it and let it run a long time at full speed and full power it melts riser cables

Here goes nothing. All answers are ignoring a really important piece of information.

what is your os?

windows often allows settings for gpu to drop.

Thus the card draws max.

I have 2 pcs that have a card that run windows 10 and use msi afterburner.

Both of these cards go run away and pull 190 to 215 watts.

So if you run windows with risers powered by sata and or molex they can burn 🔥 melt the cables.

If you run linux I run smos run away wattage almost never happens.

that means using two risers on your molex cables and 1 riser on your sata cables should be safe.

That psu has two molex cables and 2 sata cables so in theory you could attach up to six risers safely if you use smos or hiveos a linux os.

next problem is what are your cards.

I have a stud 3060ti it is the aorus and can pull 215 watts.
It has two eight pin jacks.

I have two evga 3060 ti they can only pull 190 watts.

I have three 3070

one pulls 195 watts
one pulls 200 watts
one puls 210 watts

note all cards above are when runaway wattage happens.

all cards above did this on windows 10
along with my evga 3080 cards

none have done run away on my smos setups.

makes it hard for me to tell you
a single sata cable is safe for one riser
a  molex cable is safe for for two risers.

the reality is for 3060ti and 3070 they should be safe if you set power to 130 watts on a linux os.
and on a windows 10 they are not as safe no matter how you set you clocks since on windows clocks drop out.
 

Power draw depends entirely on the graphics card and there are many that pull more than the specified 75W. But I don't know if risers that use e.g. USB cables actually do deliver 75W over the USB cable. I always was under the impression that modern risers don't take power from the motherboard at all and use their power connector to deliver power to the GPU. BUt I might be wrong, a clarification on that question would be nice.
Molex-4-pin is safe if it's a well built adapter that uses original Molex connectors and thick enough cables. I wouldn't use flimsy 3$-adapters from China indeed.

I don't like these splitters as the 6-pin connector is designed for 150W and the 8-pin connectors are designed for 225W. So theoretically you could send 450W via a connector that is rated at only 150W. Bear that in mind. Should be fine for powering the risers but don't connect powerhungry GPUs to those splitters.

the riser only consume around 15watt or less, and dont use molex to pcie, it will burn your cable, better to buy pcie spliter can handle up to 150w for safe long term use, or buying other pcie cable

See https://en.wikipedia.org/wiki/Molex_connector
That's 132W and the cables get 30°C hotter. Two risers pulling 75W each would push it. If you feel lucky, go ahead, if you wanna be safe, get a different PSU. Some cards pull more than 75W from the slot. 

What about sata to 6 pin, which comes with many risers.


Is this safe/ok to use?

I use molex to power the risers and PCIE to power cards.  Never had an issue.  Of course, don't mix  the power supplies to the same card/riser

You should be fine, update the bios to the lastest if all the PCIe slits don't work and make sure you use risers to power the graphic cards to get better cooling temperature, drop your feed back when you set things up and running

They work.  Can probably only run one in the system.  But that would get you 4-5 gpus instead of 2. 

Şimdi arkadaş yurdumuza yaşadığı ülke neresi bilmiyoruz ama gelirken muhtemelen döviz e getirecek. Biz kendi durumumuzu arkadaşa uygulayınca gelme diyoruz. Ya elinde dolar euro var ise alsana kral gibi yaşanacak pahalı ama gelen için ucuz bir ülke. Hoş geldin sefa geldin. Takma elektriği kafan her ay artıyor zaten.

2021 yılı Mart ayı için vergiler dahil mesken elektrik birim fiyatı 0,7961 TL. Yani bakarsak aslında ucuz sayılmayacak bir fiyat bu bir çok ülkeye göre. Ona göre düşünün gelin derim.

Sanırım arkadaş yabancı ve translate kullanmış. Foreign derken yabancı vatandaşlığı kastetmiş diye tahmin ediyorum. Neyse sizin son cümleyi çevirsin yeter 😂😂
